OBJECTIVES: Elective abdominal aortic aneurysm (AAA) repair is beneficial when rupture is likely during a patient's expected lifetime. The purpose of this study was to identify predictors of long term mortality following elective AAA repair for moderately sized AAAs (<6.5cm dia) to identify patients unlikely to benefit from surgery.

METHODS: We analyzed 2,367 elective infrarenal (<6.5cm) AAA repairs across 21 centers in New England from 2003-2011. Our main outcome measure was 5-year survival. Cox proportional hazards analysis were used to describe associations between patient characteristics and 5-year survival.
